Directx 9.0c Need Help!

I downloaded Directx 9.0c, started to install. The files got Extracted. When it started copying the files, Windows Logo Program said it wasn't registered, blah blah blah, This software will not be installed. Contact your system Administrator. I clicked Ok, then an error came up saying Directx could not copy a required file.

Now I believe that I need to disable the Windows Logo Program. So I searched and searched, but couldn't find anything that had to do with Windows Logo Program settings. SO, could someone tell me how to disable Windows Logo Program?

I opened mycomputer ,hit the F1 key and searched this "disable Windows Logo Program?" and found this ,i think this is what you are looking for !:)
